I think resealing a cam cover is about a 4 hour job, no? It's not just like a typicle valve cover job as the cover is machined to fit that head and is an integral part of the head assembly. I haven't done it and don't intend to discourage you, just a heads up you know. There is such a wide range of abilities on this forum- easy to one is 'oh no what have I done'
to another. Having said that there's tons of help here if you need it.
